modelPIWithNonWindupLimiter
Proportional-Integral filter with non-windup limiter
Extends from Modelica.Blocks.Interfaces.SISO (Single Input Single Output continuous control block).
Information
Model to implement a Proportional-Integral filter: y Ki
- = Kp +
u s
Output limiter with anti-windup is also implemented.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real | Kp | Proportional gain | |
| Real | Ki | 0 | Integral constant |
| Boolean | noDynamics | not (Ki > 0) and not (Ki < 0) | Trivial configuration with no dynamics G(s) = k |
| Real | yMax | 1 | Upper limits of output signal |
| Real | yMin | -yMax | Lower limits of output signal |
| Initialization | |||
| Modelica.Blocks.Types.Init | initType | Modelica.Blocks.Types.Init.InitialState | Type of initialization (1: no init, 2: steady state, 3,4: initial output) |
| Real | yStart | 0 | Initial or guess value of output (= state) |
| Advanced | |||
